595 A module modeled a bit after Rails' ActionView helpers. Several small
596 functions that create HTML tags from various kinds of data sources.
600 =head2 LOW-LEVEL FUNCTIONS
604 =item C<name_to_id $name>
606 Converts a name to a HTML id by replacing various characters.
608 =item C<attributes %items>
610 Creates a string from all elements in C<%items> suitable for usage as
611 HTML tag attributes. Keys and values are HTML escaped even though keys
612 must not contain non-ASCII characters for browsers to accept them.
614 =item C<html_tag $tag_name, $content_string, %attributes>
616 Creates an opening and closing HTML tag for C<$tag_name> and puts
617 C<$content_string> between the two. If C<$content_string> is undefined
618 or empty then only a E<lt>tag/E<gt> tag will be created. Attributes
619 are key/value pairs added to the opening tag.
621 C<$content_string> is not HTML escaped.
625 =head2 HIGH-LEVEL FUNCTIONS
629 =item C<select_tag $name, $options_string, %attributes>
631 Creates a HTML 'select' tag named C<$name> with the contents
632 C<$options_string> and with arbitrary HTML attributes from
633 C<%attributes>. The tag's C<id> defaults to C<name_to_id($name)>.
635 The C<$options_string> is usually created by the
636 L</options_for_select> function. If C<$options_string> is an array
637 reference then it will be passed to L</options_for_select>
640 =item C<yes_no_tag $name, $value, %attributes>
642 Creates a HTML 'select' tag with the two entries C<yes> and C<no> by
643 calling L<select_tag> and L<options_for_select>. C<$value> determines
644 which entry is selected. The C<%attributes> are passed through to
647 =item C<input_tag $name, $value, %attributes>
649 Creates a HTML 'input type=text' tag named C<$name> with the value
650 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
651 tag's C<id> defaults to C<name_to_id($name)>.
653 =item C<hidden_tag $name, $value, %attributes>
655 Creates a HTML 'input type=hidden' tag named C<$name> with the value
656 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
657 tag's C<id> defaults to C<name_to_id($name)>.
659 =item C<submit_tag $name, $value, %attributes>
661 Creates a HTML 'input type=submit class=submit' tag named C<$name> with the
662 value C<$value> and with arbitrary HTML attributes from C<%attributes>. The
663 tag's C<id> defaults to C<name_to_id($name)>.
665 If C<$attributes{confirm}> is set then a JavaScript popup dialog will
666 be added via the C<onclick> handler asking the question given with
667 C<$attributes{confirm}>. If request is only submitted if the user
668 clicks the dialog's ok/yes button.
670 =item C<textarea_tag $name, $value, %attributes>
672 Creates a HTML 'textarea' tag named C<$name> with the content
673 C<$value> and with arbitrary HTML attributes from C<%attributes>. The
674 tag's C<id> defaults to C<name_to_id($name)>.
676 =item C<checkbox_tag $name, %attributes>
678 Creates a HTML 'input type=checkbox' tag named C<$name> with arbitrary
679 HTML attributes from C<%attributes>. The tag's C<id> defaults to
680 C<name_to_id($name)>. The tag's C<value> defaults to C<1>.
682 If C<%attributes> contains a key C<label> then a HTML 'label' tag is
683 created with said C<label>. No attribute named C<label> is created in
686 If C<%attributes> contains a key C<checkall> then the value is taken as a
687 JQuery selector and clicking this checkbox will also toggle all checkboxes
688 matching the selector.
690 =item C<date_tag $name, $value, cal_align =E<gt> $align_code, %attributes>
692 Creates a date input field, with an attached javascript that will open a
693 calendar on click. The javascript ist by default anchoered at the bottom right
694 sight. This can be overridden with C<cal_align>, see Calendar documentation for
695 the details, usually you'll want a two letter abbreviation of the alignment.
696 Right + Bottom becomes C<BL>.
698 =item C<radio_button_tag $name, %attributes>
700 Creates a HTML 'input type=radio' tag named C<$name> with arbitrary
701 HTML attributes from C<%attributes>. The tag's C<value> defaults to
702 C<1>. The tag's C<id> defaults to C<name_to_id($name . "_" . $value)>.
704 If C<%attributes> contains a key C<label> then a HTML 'label' tag is
705 created with said C<label>. No attribute named C<label> is created in
708 =item C<javascript_tag $file1, $file2, $file3...>
710 Creates a HTML 'E<lt>script type="text/javascript" src="..."E<gt>'
711 tag for each file name parameter passed. Each file name will be
712 postfixed with '.js' if it isn't already and prefixed with 'js/' if it
713 doesn't contain a slash.
715 =item C<stylesheet_tag $file1, $file2, $file3...>
717 Creates a HTML 'E<lt>link rel="text/stylesheet" href="..."E<gt>' tag
718 for each file name parameter passed. Each file name will be postfixed
719 with '.css' if it isn't already and prefixed with 'css/' if it doesn't
722 =item C<date_tag $name, $value, cal_align =E<gt> $align_code, %attributes>
724 Creates a date input field, with an attached javascript that will open a
725 calendar on click. The javascript ist by default anchoered at the bottom right
726 sight. This can be overridden with C<cal_align>, see Calendar documentation for
727 the details, usually you'll want a two letter abbreviation of the alignment.
728 Right + Bottom becomes C<BL>.
730 =item C<tabbed \@tab, %attributes>
732 Will create a tabbed area. The tabs should be created with the helper function
736 L.tab(LxERP.t8('Basic Data'), 'part/_main_tab.html'),
737 L.tab(LxERP.t8('Custom Variables'), 'part/_cvar_tab.html', if => SELF.display_cvar_tab),
740 An optional attribute is C<selected>, which accepts the ordinal of a tab which
741 should be selected by default.
743 =item C<areainput_tag $name, $content, %PARAMS>
745 Creates a generic input tag or textarea tag, depending on content size. The
746 amount of desired rows must be either given with the C<rows> parameter or can
747 be computed from the value and the C<cols> paramter, Accepted parameters
748 include C<min_rows> for rendering a minimum of rows if a textarea is displayed.
750 You can force input by setting rows to 1, and you can force textarea by setting
753 =item C<multiselect2side $id, %params>
755 Creates a JavaScript snippet calling the jQuery function
756 C<multiselect2side> on the select control with the ID C<$id>. The
757 select itself is not created. C<%params> can contain the following
764 The label of the list of available options. Defaults to the
765 translation of 'Available'.
769 The label of the list of selected options. Defaults to the
770 translation of 'Selected'.
774 =item C<sortable_element $selector, %params>
776 Makes the children of the DOM element C<$selector> (a jQuery selector)
777 sortable with the I<jQuery UI Selectable> library. The children can be
778 dragged & dropped around. After dropping an element an URL can be
779 postet to with the element IDs of the sorted children.
781 If this is used then the JavaScript file C<js/jquery-ui.js> must be
782 included manually as well as it isn't loaded via C<$::form-gt;header>.
784 C<%params> can contain the following entries:
790 The URL to POST an AJAX request to after a dragged element has been
791 dropped. The AJAX request's return value is ignored. If given then
792 C<$params{with}> must be given as well.
796 A string that is interpreted as the prefix of the children's ID. Upon
797 POSTing the result each child whose ID starts with C<$params{with}> is
798 considered. The prefix and the following "_" is removed from the
799 ID. The remaining parts of the IDs of those children are posted as a
800 single array parameter. The array parameter's name is either
801 C<$params{as}> or, missing that, C<$params{with}>.
805 Sets the POST parameter name for AJAX request after dropping an
806 element (see C<$params{with}>).
810 An optional jQuery selector specifying which part of the child element
811 is dragable. If the parameter is not given then it defaults to
812 C<.dragdrop> matching DOM elements with the class C<dragdrop>. If the
813 parameter is set and empty then the whole child element is dragable,
814 and clicks through to underlying elements like inputs or links might
817 =item C<dont_recolor>
819 If trueish then the children will not be recolored. The default is to
820 recolor the children by setting the class C<listrow0> on odd and
821 C<listrow1> on even entries.

846 After dropping e.g. the third element at the top of the list a POST
847 request would be made to the C<reorder> action of the C<SystemThings>
848 controller with a single parameter called C<thing_ids> -- an array
849 containing the values C<[ 6, 2, 15 ]>.
853 Dumps the Argument using L<Data::Dumper> into a E<lt>preE<gt> block.
857 =head2 CONVERSION FUNCTIONS
861 =item C<options_for_select \@collection, %options>
863 Creates a string suitable for a HTML 'select' tag consisting of one
864 'E<lt>optionE<gt>' tag for each element in C<\@collection>. The value
865 to use and the title to display are extracted from the elements in
866 C<\@collection>. Each element can be one of four things:
870 =item 1. An array reference with at least two elements. The first element is
871 the value, the second element is its title.
873 =item 2. A scalar. The scalar is both the value and the title.
875 =item 3. A hash reference. In this case C<%options> must contain
876 I<value> and I<title> keys that name the keys in the element to use
877 for the value and title respectively.
879 =item 4. A blessed reference. In this case C<%options> must contain
880 I<value> and I<title> keys that name functions called on the blessed
881 reference whose return values are used as the value and title
886 For cases 3 and 4 C<$options{value}> defaults to C<id> and
887 C<$options{title}> defaults to C<$options{value}>.
889 In addition to pure keys/method you can also provide coderefs as I<value_sub>
890 and/or I<title_sub>. If present, these take precedence over keys or methods,
891 and are called with the element as first argument. It must return the value or
894 Lastly a joint coderef I<value_title_sub> may be provided, which in turn takes
895 precedence over each individual sub. It will only be called once for each
896 element and must return a list of value and title.
898 If the option C<with_empty> is set then an empty element (value
899 C<undef>) will be used as the first element. The title to display for
900 this element can be set with the option C<empty_title> and defaults to
903 The option C<default> can be either a scalar or an array reference
904 containing the values of the options which should be set to be
907 =item C<tab, description, target, %PARAMS>
909 Creates a tab for C<tabbed>. The description will be used as displayed name.
910 The target should be a block or template that can be processed. C<tab> supports
911 a C<method> parameter, which can override the process method to apply target.
912 C<method => 'raw'> will just include the given text as is. I was too lazy to
913 implement C<include> properly.
915 Also an C<if> attribute is supported, so that tabs can be suppressed based on
916 some occasion. In this case the supplied block won't even get processed, and
917 the resulting tab will get ignored by C<tabbed>:
